This plant has pale flowers. When they fall, thick red cups are left. People pick the cups and dry them.
In hot water, the dry cups make a bright red drink. It tastes sour, a bit like cherries. People drink it hot or cold in many hot countries.

| Heart & blood vessels | 🟡 Some evidence (small human studies) | A 2022 meta-analysis of 17 trials found hibiscus lowered systolic blood pressure by about 7 mmHg versus placebo, most in people with raised blood pressure, and slightly lowered LDL cholesterol[1]. A stricter Cochrane review found only one eligible trial and judged the evidence insufficient[2]. |
